Problems while returning several values in a function?

Question

I am returning several values in a function:

def count_chars(e):
    return len(e), 'bar'

like this:

for d in lst:
    newlst = []
    for x in d["data"]:
        newlst.extend([x, count_chars(x)])
        d["data"] = newlst
pprint(lst)

However, when I return the values the come inside a tuple:

{'data': ['YES', (9, 'bar')], 'info': 'AKP'}

How can I get rid of the tuple? for

{'data': ['YES', 9, 'bar'], 'info': 'AKP'}

Unpack the function result (which is a tuple) with the * operator:

newlst.extend([x, *count_chars(x)])

That syntax is only available in Python >= 3.5. Otherwise you can use simple concatenation:

newlst.extend([x] + list(count_chars(x)))
